Could we feed methane to cows? Study tackles two climate issues in one
New Zealand's ruminant cows and sheep contribute much of our greenhouse gas emissions by belching methane into the air.
But what if we flipped the paradigm and fed them methane instead?
We know methane and carbon dioxide are potent greenhouse gases that drive climate change, and are common by-products from industrial processes.
Although about a third of our emissions come from transport and electricity generation, the greatest proportion - around half of the inventory - comes from agriculture, and much of that from methane belched from ruminant livestock like sheep and cows.
